Cylinder gas distribution type two-stroke engine

Abstract

A two-stroke engine of cylinder valve actuating type is prepared as forming valve actuating mechanism by one work cylinder and a numbers of valve actuating cylinders, connecting two types of said cylinders in parallel way and setting air door between them, arranging air channel at top of valve actuating cylinder and air inlet of work cylinder at one side of combustion chamber for coordinating it with air outlet through air door and valve actuating cylinder, setting air exhaust of work cylinder at middle part of work cylinder and setting link piston of both said cylinders on the same crank shaft.

Description

technical field [0001] The invention relates to a reciprocating piston type internal combustion engine, in particular to a cylinder gas distribution type two-stroke engine, which belongs to the technical field of international patent classification F01813 / 00 "cylinder type reciprocating piston type machine or engine". Background technique [0002] The four-stroke engine has been widely used in various vehicles such as automobiles and engines. Each working cycle includes four piston strokes: intake, compression, power, and exhaust. Each stroke occupies a 180° crankshaft angle. The structure is relatively Heavy and complicated, there is only one working stroke in the four piston strokes, and the rest are all power-consuming strokes. The two-stroke engine can do twice as much work per unit time as the four-stroke engine, and has a simple structure and is easy to use and maintain. Its shortcoming is that there is no special intake and exhaust stroke, and the time of the ventila...

Problems solved by technology

[0002] The four-stroke engine has been widely used in various vehicles such as automobiles and engines. Each working cycle includes four piston strokes of intake, compression, power, and exhaust. Each stroke occupies a 180° crankshaft angle. The structure is relatively Heavy and complicated, there is only one power stroke in the four piston strokes, and the rest are power consumption strokes

Its disadvantage is that there is no special intake and exhaust stroke, and the time of the ventilation process is short. It uses fresh air to sweep away the exhaust gas. The loss of new air is large, and the exhaust gas is not easy to clean. The intake air is insufficient, and the combustion chamber is relatively hot, which directly affects the engine. work stability and power output, making power and efficiency relatively low
